To all whomm't may concern." 1

Be it known that I, SAMUEL I. 'PATTON, citizen of the United States of 7 America, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements .in lVin'dow- Screen Fasteners, of which the following is a specification.

This invention relates to'new and useful improvements in window screen fasteners.

It is customary to hinge full-length win-- the dew screens at the top and to swing same outwardly at the bottom, when it is desired to. open or remove the screen. Va rious devices for fastening the bottom of the, screen have been used such ashooks and eyes and hook bolts and pins. With such devices it is impossible'to tightly fasten the screen or to draw the bottom of the screen against. the sill, particularly after the wood.

has swelled or settled.

It is the object of my invention to provide a fastener for securing the bottom of a hinged window screen firmly against the sill and having provision for compensating such irregularities as occur from varying thickness of wood, swelling, contracting and settling of the house. 3

A particular ob'ect is to provide a fastening device comprising a fixed element secured to the window frame and a rocking element attached to the screen and having a wedging or cam action, when engaged with the fixed element, whereby the screen is drawn tightly against the sill under varying conditions.

A further object is to provide a simple fastener constructed to be readily and quickly installed and easily operated; and the parts of which may be inexpensively produced.

A'construction designed to carry out the contracted or the house has invention will be hereinafter described togetlier with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein: Fig. 1 is a partial inner element of a window frame and screen provided with v a fastener constructed in accordance with my sheet 'metal.

invention, the fastener being disengaged and the screen free to swing open,

Fig. 2 is a similar view showing the fastener engaged and the screen fastened, Fig. 3 is a vertical sectional view on the line 33 of Fig. 1,

Fig. 4 is a cross-section on the line 4 -1- of Fig. 1, Fig. 5 is a perspective view of the pin, and Fig 6 is a perspective view of the latch.

In the drawings the numeral 10 designates the ear of a latch 11 and is bentat right angles from the central portion thereof. The latch is provided with a curved finger 12 having its inner edge 13 inclined inwardly and offset from the ear. A curved handle 14 is provided on the opposite end of the latch.

This latch may be cast or stamped from The ear has a central eye 15 for receiving a, screw 16, which latter is screwed into the inner face of the side rail A of a window screen, said screen being hinged at its upper end in a suitable manner. The latch is left free to rotate around the screw. I

A wedge'pin or keeper 17 is driven into the side of the window frame B, against which the screen closes. The pin is disposed horizontally and in juxtaposition to the latch, so that it is received between the finger 12 and the ear rotated to latch the screen. It will be seen that when the latch is swung in a counter- 10 when said latch is clockwise direction, by moving the handle eye to the'inner end of the finger. Con sequently'when the latch is swung, the edge 13 rides outwardly on the wedge pin and amplifies the lateral displacement of the latch, ,thus securely fastening the screen. The latched position is shown in Fig. 2, but

and neat in appearance.

Various changes inthe size and shape of the different parts, as well as modification and alterations may he made within the scope of the. appended claims.

lVhat I claim, is:

1. In a window-screen latch, a rotatable The latch is easilv manipulated and is small latch member having a. finger provided with aninclined edge and a wedge pin engaged This provides for by said inclined edge when the latch is rotated.

2. In a Window screen latch, a rotatabletlatch member having a curved-finger providedl witl1.;ani inclined .edge, and a driven wedge pin engaged by said inclined edge when thelatch is rotated.

3. In a window screen latch, arotatable latch member having a curved finger provided with;airinclined edge, and a driven wedge pin engaged by said inclined edge when the latch isurotated, said finger being curved eccentrically to the pivot of the latch,

whereby said inc'linedtedge-.ridesalong the edge o'fihewedgiepin. as the latch :is rotated. In testimony whereof I. zaflix, .1ny1signa-.
